Reinforcement and applying rust protective chemical: If old bearing pedestal is to be fixed up, the broken surface area shall be thoroughly cleaned by wire brush to eliminate loose rust particles then exposed support shall be cleaned of all rust and millscale by mechanical wire brush, to removal of oil or oily residues and also the loss of reinforcement will be compensated by tying of brand-new reinforcement.

The reinforcement's rust, if any, will be gotten rid of by applying rust removal, chemical (Reebaklens RR of Fosroc or comparable product of BASF or Sika) and cleaning of reinforcement with a mechanical wire brush. After that using one coat of zinc rich covering of Nitozinc Guide of Fosroc or equivalent item of BASF or Sika).

Micro-concrete: Flowable mix of 1part by weight of Micro-concrete power, 1 part by weight of grit/Aggregate (approximately 10mm) and essential water needed for workability. The mix shall be blended completely by mechanical stirred for about 3 mins. D. Applying: After supplying necessary water tight shuttering, the flowable mix ought to be poured and there is no requirement for compaction as it is flowable and self compacting mix.

Treating: The curing of pedestal will be provided for at least 7 days. Upkeep of bridge bearings: 1. Surrounding of  Full Article  shall be cleared of silt and particles. 2. In case of POT-PTFE bearings, I have noticed in some cases that short-term clamp did not detach after setup of the bearing.

So after installation of POT-PTFE bearings, You need to take note of disconnect the short-term clamp. 3. In case of metal bearings, dirt, rust and deterioration are typical treatments due to weather impact. For Bearing rust elimination and Cleaning/repainting: The following stepwise treatment is to be followed: A. The location around the bearings and their pedestals shall be cleared of all debris, plants, dust, and so on.

B. Fresh graphite grease as approved by the Engineer shall be applied to the surfaces which are siding, rotating or moving due to movement in bearings. C. All other surfaces of the metal bearing will be cleaned of all rusts, corrosion and a coat of anticorrosive oil paint used.
